مثال التعليمة البرمجية

// create an AudioListener and add it to the camera const listener = new THREE.AudioListener(); camera.add( listener ); // create the PositionalAudio object (passing in the listener) const sound = new THREE.PositionalAudio( listener ); // load a sound and set it as the PositionalAudio object's buffer const audioLoader = new THREE.AudioLoader(); audioLoader.load( 'sounds/song.ogg', function( buffer ) { sound.setBuffer( buffer ); sound.setRefDistance( 20 ); sound.play(); }); // create an object for the sound to play from const sphere = new THREE.SphereBufferGeometry( 20, 32, 16 ); const material = new THREE.MeshPhongMaterial( { color: 0xff2200 } ); const mesh = new THREE.Mesh( sphere, material ); scene.add( mesh ); // finally add the sound to the mesh mesh.add( sound );
